GLOVE-SEWING MACHINE.

SPECIFICATION forming part of Letters Application filed July 29, 1882.

Patent No. 265,451, dated October 3, 1882.

(No model.)

To all whom it may concern:

Be it known that I, JOHN SIMON, of the city, county, and State ofNewYork, have invented certain newand useful Improvements in Glove- SewingMachines, of which the following is a specification.

This invention has reference to an improved machine forsewinggloves,furs, and other articles in which an overseain stitch isrequired, the machine being composed of the well-known elements ofglove-sewing machines-that is to say, of two parallel feed-disks, areciprocating needle, and an oscillating looper-which, however, areworked by actuating mechanism of great simplicity from a cam-shaftarranged longitudinally and parallel to the axis of the machine; and theinvention consists in the peculiar construction of the differentactuating mechanisms, whereby the parallel feed-disks, reciprocatingneedle, and oscillating looper are operated, as will more fully appearhereinafter, and finally be pointed out in the claims.

In theaccompanyingdrawings, Figurelrepresents a vertical longitudinalsection of my improved glove-sewing machine. Fig. 2 is a detail top viewofthe sewing mechanism-40 wit, the feed-disks, reciprocating needles,and the looper, which is shown in section. Fig. 3 is a plan view of themachine with the top part removed. Fig. 4 is a detail view of themechanism for imparting an axial motion to the guiderod of the looper.Fig. 5 is a detail view of the mechanism for imparting a verticaloscillation to said guide-rod. Fig. 6 is a detail view of the cam and ofa part of the lever which imparts motion to theinner feed-disk. Fig. 7is an end elevation of the machine.

Similar letters of reference indicate corresponding parts. I

By referring to the drawings, which fully illustratemyinvention,Arepresents an oblong casing, which is supported on a strongstandard,A. The casingAinclosesactuatingmechanisms of the parallelfeed-disks, the reciprocating needle,and the oscillating looper,whichlatter are arranged outside of and at one end of the casing A. ThecasingAis closed by a top plate, A on which the customary thread-holding and tension devices for this class of machines are arranged.

The shaft of the inner feed-disk, B, is supported on vertical bearingsof a bracket, B

I attached to the end wall of the casing A, and held in position bymeans of a nut atit-s lower end. The circumference of the feed-disk B ismilled in the usual manner, so as to engage by friction thecircumference of the second feeddisk, B. The feed-disk B is supported inbearings at the lower end of an angular arm, 0, which slideslongitudinally in the casing A parallel to the driving-shaft, the outerfront end of said arm extending longitudinally forward, thencevertically downward, thence horizontally sidewise, and thence verticallyupward. This arm is acted upon at the interior spring, 0, one end ofwhich bears against a transverse pin, a, of the arm, while the other endis steadied against the fixed guide-socket (l of the casing, as shownclearly in Fig. 3. The spiral spring tends to press this rod inward, andconsequently to keep the outer feeddisk in frictional contact with theinner feeddisk, so that the former turns simultaneously with-the latter,but in opposite direction th ereto. The circumference of the outerfeed-disk, B, is also milled or serrated, so that the goods are properlytaken holdofin being fed through between the disks.

All the operating parts of my improved glove-sewing machine receivemotion from a driving cam-shaft, D, the axis of which is arrangedparallel to the longitudinal axis of the machine, said shaft beingextended to the outside of the casing A and provided with a flywheel, Dand apulley, D, to which latter motion is imparted by a belt from atreadleor power shaft, as the case may be. The inner feed-disk, B,receives intermittent axial motion from an angular lever, B, which isoperated by a cam, B, on the driving-shaft D. This angular lever ispivoted to and supported by a short arm, B attached to a ring, B whichis loose on a boss connected to the disk B. The horizontal upper arm ofthe lever B projects through a slot in the front end of the casing A,and its outer end is adapted to bite below and integral with the disk B.The vertical arm of said lever is curved and rests against the cam B. Asthe projecting face of of the casing by a strong expansive spiral'against a milled or toothed disk, B which is IOu milled disk B As thecam, by its increasing eccentricity, continues its pressure upon thelever B the latter is carried bodily on its movable pivot a suflicientdistance to impart the necessary feed-motion to the disks. As theprojecting face of the cam recedes from the curved vertical arm of thelever the weight of said arm causes the lever to turn on its pivot, soas to release the disk B and a spring, 13, one end of which is attachedto the casing A, while the other end presses against the arm B returnsthe lever to its normal position, the arm B resting against the end ofan adjustable stop, S. This stop is slotted at one end and attached tothe front side of the casing by means of a set-screw, 0. By theadjustment of this stop the movement of the disks, and consequently thefeed of the fabric, may be regulatcd.

1t it is desired to release the fabric from the feed-disks, the outerfeed-disk is moved forward away from the inner disk by means of a leveroperated by a treadle, as shown in dotted lines in Fig. 1, the upper endof said lever being connected to the rod 0, to which said disk isattached.

The horizontally'reciprocating needle E is operated by a horizontalneedle-bar, E, which is guided in bearings formed in the end walls ofthe casing A, said needle-bar having a downwardlyprojecting pin, E whichis engaged by a grooved cam, E The needle-bar is provided at its outerend with a socket or fastening devices for the needle, and with meanswhereby the thread is guided and conducted to the eye thereof.

The complex motion of the looper F is obtained by thejoint action ofamore complicated mechanism. This looper is socketcd in the outer end ofa slightly-inclined looper-rod, F, which passes through slots in the endwalls of the casing A, and which is supported by a pivoted socket, F Thefirst motion imparted to the looperis a longitudinal reciprocatingmovement, which is effected by means of a pendulous lever, Gr,fulcrunied at its upper end to the casing, and operated at its lower endby a grooved cam, G, being connected about mid way of its length to thelooper-rod by a pin, (1, which passes through lugs attached to said rodand through an eye, (1, on said lever. The second motion imparted to thelooper is a vertical movement, which is produced by the action of asleeve, 11, on the looper-rod F, the vertical shank of which sleeve isguided in a fixed socket, 11, supported by a bracket attached to thefront end of the casing, said shank passing through the slottedreciprocating needle-bar, and resting at its lower rounded end on apeculiarly-recessed cam, I, on the shaft D, whereby, in connection withthe pivoted supporting-bracket, a vertical oscillation of the looper-rodis obtained. The lateral motion of the looper is accomplished by anaxial turning of the looper-rod, which is effected by an arm, J,adjustable on said rod, a recessed cam, K, on the driving-shaft, and aspring, L,

which holds the lower end of the arm in contact with the cam. This arm Jis composed of two members hinged together, so as to permit thelooper-rod to move endwise. The three different motions described, whichare imparted to the guide-rod F of the looper F-to wit, theforward-and-backward motion, the vertical oscillating motion, and theaxiallyturning motion-impart together the peculiar complex motion whichthe looper requires in taking up the thread and turning the same overthe seam of the glove or fur, and by which the loops are tightened readyfor the next stitch of the needle. The stitching-thread is stretched bythe forward motion of the needle-bar, so as to bind off and tighten theloop. For this purpose the needle is guided in a radial recess orimpression in the outer feed-disk, B. The looper is released before theloop is finally completed, so as to be ready to be returned to the otherside of the seam for taking up the thread after the needle has passedthrough, bringing the thread over the same to be bound off.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of the rotary feed-disks, thereciprocatory needle, the looper having a longitudinal, a vertical, anda lateral movement, a driving-shaft parallel to the needle, a series ofparallel cams on said shaft, and mechanism connecting said cams with thefeed-disk, needle, and looper, respectively, substantially as described.

2. The combination of the needle, the looper, the rotary feed-disks, andthe mechanism for actuating said disks, consisting of a toothed diskattached to the inner feed-disk, a loose ring on a boss of the disk,provided with a projecting arm, an angular lever pivoted to said arm,the outer end of said lever being adapted to engage the toothed disk, acam for operating the lever, and a spring which bears against theprojecting arm and returns the parts to their normal position after theyare acted upon by the cam, substantially as specified.

3. The combination, with the rotary feeddisks, of the toothed disk B thering 13, provided with arm 13, the angular lever B, pivoted to said arm,the cam 13, the spring B, and the adjustable stop S, substantially asdescribed.

4. The combination, with the looper-rod and looper, of an articulatedlever, J, spring L, and cam K, whereby the looper-rod is made tooscillate axially and permitted to reciprocate longitudinally,substantially as specified.

5. The combination, with the looper-rod and looper, of the lever G, camG, sleeve H, socket H, recessed cam I, articulated lever J, cam K, anddriving-shaft D, substantially as set forth.

In testimony that I claim the foregoing as my invention 1 have signed myname in pres ence of two subscribing witnesses.
